PC/ABS silver streak (degradation type)
문제 현상
Shiny silver streaks still appear after full drying, reduced after lowering temperature.
원인 분석
Too high melt temperature or too long residence time degrades material and produces gas; shear overheating also produces shiny silver streaks.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
해결 방법
①Reduce melt temperature by 10~15℃; ②shorten residence time; ③reduce screw speed; ④verify variable by variable for confirmation.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Degradation-type silver streaks are shiny and drying is ineffective; temperature reduction verification is the identification method.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
